. 1 Y e This invention-relates to anapparatus for use in measuringliquids such as acidl and more particularly to an apparatus of extremelysimple construction capable of being employed for accurately measuringdesired quantities of a liquid and lwhich is so constructed that it maybe readily assembled and disassembled for the re' placement of partsthereof and for varying 'the capacity of the apparatus.

Still a further object of the invention is to provide a measuringYapparatus mounted for oscillating movement and so that a container'maybe readily positioned to receive a measured quantityHf-71iquiddischarged therefrom and thereafter readily removedfrombeneath the apparatus. 7 Varios'other objects and advantages oftheinvention'will hereinafter become more fully ap- Y'parent from thefollowing description of the drawing, illustrating apresently preferredem bdiment thereof, and wherein; f VFigure 1/ is a side elevationalnviewof the 'measuring apparatus;

Figure 2 is anenlarged vertical sectional'view, partlyin side elevationthereof, and f-Figure 3 'is an enlarged fragmentary horizon- -talsectional view of a portion vofthe-apparatus. Referring morespecically'to the drawing, the --liquid measuring apparatus in itslentirety is designated generally 5 and includes a stand, designatedvgenerally 6,- composed of a pair of correspondingsupporting standards 41each of which -is provided at itslower-end with an elongated foot 8adapted to rest on va supporting surfaces for supporting its standardlin an upright Lposition. Each standard 1 is provided at its upperendwith an inwardly extending bearing I0. .The-bearings Ill are disposed inalignment and a cup-shaped holder II having an'open top is disposed.between. the Y upper portions ofthe `standards 1 andthe bearings Illandis provided L f1 claim. (ol. 222-453) vbearings I0 for supporting theholder between the standards 1- for v rocking movement relatively-thereto.` The terminals of the trunnions I2 are'Av threaded as seen atI3 toreceivenuts I4 fordeitachably. connectingthe holder 'I I Vtothe-statici#` ard 1 and .which are adapted to be tightenedv sumcientlyto maintain the standards 1 in upright positionsfbut 'to lpermit theholder `I I; to 'rockAf .relatively thereto. Y Y A: storage containerI5, such as a bottle or'jar whichis preferably formedof,l glass oriother f transparent material, is demountable 'supported vv,1n the'holder- Il and extends upwardly from the` 'sagef 28 extendingthereacross and havi' insure registration of the passages 24 andf'oneposition ofsliding movement o fth'erod fzlii .A- measuringcontainer, designatedfgenerally 29, preferably formed of glass or otherytransparentn 1ate1 ial, is provided at its upper end j open top thereofand is provided atitsfend with a filling neck I6 normally V4closed'by a'plug sage I8. The jar or bottle I5 is of a proper cross sectional sizeand shape to fit into the'holder` H and is provided with a relatively`thick bottomlil having a depending'externally threadednpple 20 whichextends downwardly...v therefrom through an opening 2| in the bottom'122'Ofthe holder II. The bottom I9 hasa bore 23 extending therethrough andlongitudinally through-the nipple 20. Said bottom I9 is also providedwith av passage 24 having 'a diagonalllowersportion which opens into thebore 23 intermediateloff. its ends and an upperportion whichis disposedsubstantially paralleli tosaid bore' '23fland1which opens into theinterior of the container-d; The. nipple 20 is provided with aninternallngitudinally Vextending groove 25 which ,opens into' the bore23 and which extends from the lower fopen end of saidnipple upwardlypreferably intova'p'o'rtion` of' the bottom I9.- e. .v

An elongated rod 26 is sized` tos'lidablyr-en'gage in the bore 23 and isdisposed inrelatlvely 4snug fitting engagement therewithf and' with fitsupper end disposed in the upperportionof saidzzbore23 and'above theupper end of the groove 25... A-ipin vor key 21 projects radially fromthe rod- 2E and sli'dablt7V engages theA groove '25l to vkey Ather-fredyto the container I5 to prevent itfrom rotating fin the bore 23;however, lif said rod andthebore23 are of non-circularcross `section thegroove2 5 and key 21 may be omitted. lThe rod 26,` adjacent its upper`end, is provided with al diagona "pasupper end disposed in one slidingposition offthe rodv 2t toV register' withv the lower, diagnal end ofthe passage 24.

The lower portion of the rod 26 is provided witha longitudinally extending bore 36 having a radially extending upper end31 which opens outwardly of the periphery n thereof to register with oneend of the passage 34 in one position of the rod 26 relatively to themeasuring container29. The bore 36 extends longitudinally throughv therestricted rod portion 35 to adjacent the lower end thereof. The rodportion 35 adjacent its lower, closed end is pr`o f vided with aplurality, preferablyfour circumferentially spaced radially extendingapertures or bores 38 which open outwardly of the rodV portion 35 andwhich communicate with the bore-36 to form the discharge ports of themeasuring apparatus 5.

The rod 26, directly above its restricted end 35, bis; externally.:threaded as `:seen at 3 9` to Yreceivev a '.nut or threaded collar ..40which is adjustably mounted :thereon .and whichl provides a seat vfor l...the Alowerrend of an expansion coil spring- 4I.
